NEW OR NOTEWORTHY FUNGI 15 



well founded, it would seem that all the following names apply to 

 varying states of one species : Trichothecium rosewn, T. candidum, 

 T. ohovatum, Cephalothecium roseum, C. candidum, Arthrobotrys 

 superba, A. oUgospora, A. rosea, not to mention others. Nothing 

 but cultures under diverse conditions can decide this point ; the 

 differences given in systematic works, including the dimensions 

 of the conidia, are of the kind that I have found to vary in a 

 single growth. 



DIDYMOCLADIUM Sacc. Fertile hyphae erect, divided 

 above into branches arranged in whorls of three. Conidia on 

 the inflated tips of the branchlets, ellipsoid, 1-septate, hyaHne, 

 catenulate. 



152. DiDYMOCLADiuM TERNATUM Sacc. Syll. Fuug. iv. 187 ; 

 Trans. Brit. Myc. Soc. i. 114. 



Tufts woolly, white ; hyphae ascending, sparsely septate, with 

 few subopposite or ternate branches, passing into ternate filiform 

 branchlets, which are inflated at the summit. Conidia ellipsoid, 

 1-septate, at length constricted, hyaline, in long chains. 



On Stereum and Polyponcs, Packington Park (Wk.), July, 1886. 



153. Eamularia taraxaci Karst. Sacc. Syll. Fung. iv. 207. 

 Epiphyllous, spots small, roundish, with purple margins, like 



those of Ovularia obliqua. Hyphae in little tufts, simple or with 

 one or two very short branches at the summit, hyaline, occasionally 

 septate, averaging 50 x 3-4 /x. Conidia occasionally in short 

 chains, at first continuous, then 1-3-septate, up to 30-32 /x long, 

 3-5-4 fx broad. (Tab. 515, fig. 11.) 



On leaves of Taraxacitm, Lodge Hill, Selly Oak (Ws.), 

 September. 



154. Eamularia primula Thiim. Sacc. Fung. Ital. t. 985 ; 

 Syll. Fung. iv. 214. 



Tufts minute, crowded on pale patches, without a conspicuous 

 border, chiefly epiphyllous ; hyphae 60-70 X 4 /x, continuous, 

 rarely branched, bearing a few cylindrical, slightly fusoid conidia, 

 which are continuous, hyaline, and about 25 x 4 /x. (Tab. 515, 

 fig. 8.) 



As stated above under Ovularia primulana, I have found a 

 fungus agreeing with this description, but also exhibiting a much 

 more mature form as there described. The one described here is 

 intermediate between the two extremes. 



TEINACRIUM Eiess. Hyphae thin, filiform, continuous, 

 mycelium creeping, almost non-existent. Conidia triradiate, 

 hyaline, radii cylindrical, 2-pluriseptate. 



155. Trinacrium subtile Eiess in Fres. Beitr. p. 42, t. 5, 

 f. 14-17 ; Sacc. Syll. Fung. iv. 231 ; Fung. It. t. 966. 



Conidia triradiate, radii 30-35 (or even 40) X 4 /x, 4-5-septate, 

 tapering gradually from the base, not constricted at the septa. 



On the hymenium of Peniophora rosea, Eardisland (Hereford), 

 August. Eays occasionally even 6-septate.
